CONNECTING WITH UPS
It is recommended that, if the power of the servers connected to the server switch unit is supplied from
a UPS (uninterruptible power supply), the power of the server switch unit is supplied from the UPS.
IMPORTANT：Connect the server switch unit with UPS having the
highest boot priority within the system. If any server connected to the
server switch unit starts in prior to the server switch unit, the server
switch unit may fail to operate correctly.
SETTINGS FOR MOUSE ON REDHAT LINUX 7.2
When connecting the server switch unit to the server on which RedHat Linux 7.2 is installed via the
dedicated cable K410-118, RedHat Linux 7.2 may fail to detect the mouse device.
In such a case, change the settings of RedHat Linux 7.2 as described below.
1. Check if the symbolic link for the device has been created on the shell prompt. (Type the
underlined character strings.)
[root@localhost]# ls -l /dev/mouse
<Enter>
If the message "No such file or directory" appears, create the symbolic link as shown below.
2. Create the symbolic link for the mouse device.
[root@localhost]# cd /dev
<Enter>
[root@localhost]# ln -s input/mice mouse
<Enter>
NOTE：You need to log in the system as the user with administrator
authority (root) to create the symbolic link.
